New causes of the extinction that occurred in the oceans after an asteroid impact 65 million years ago

The study, published by Laia Alegret, Ellen Thomas and Kyger C. Lohmann, shows that the photosynthesis and the food chain in the oceans recovered much earlier than previously suggested. A rapid episode of surface ocean acidification after the impact may have been the main cause of extinction of numerous species, while taxa that lived at the deep sea floor survived.

Confirmed: the Chicxulub impact caused the K/T extinction

Members of the IUCA and the Team of Micropaleontology of the Universidad de Zaragoza, along with 38 other specialists, publish in the prestigious Journal Science a review corroborating the theory that the impact of a large meteorite in the Yucatan peninsula caused the mass extinction event of the Cretaceous/Tertiary boundary. The alternative hypothesis supporting a more gradual extinction due to multiple causes (mainly to the unusual volcanic activity of the Deccan, India) is weakened.

Eustoquio Molina was elected as a member of the Real Academia de Ciencias

Eustoquio Molina was elected as a member of the Real Academia de Ciencias de Zaragoza in October 2015 and made his admission speech as a numerary member, in June 2016. Photo with the president of the Academy after the delivery of the medal and the diploma.

Portada del libro 'Micropaleontología'The members of the Team of Micropaleontology of the University of Saragossa constitute the majority of the members of the Consolidated Group of Research EO5: " Extinction and paleoenviroment reconstruction from Cretaceous to Quaternary ", recognized by the Government of Aragon.

Our researches have solved different problems: bio-chronoestratigrafic, paleoecologic, evolutionary and extinction, based on the study of planktic and small benthic foraminifers, mainly from the Upper Cretaceous (Coniacian) to the Lower Neogene (Langhian).

Besides publishing numerous articles in prestigious journals, one of the main publications of the group has been a text book of Micropaleontology, Prensas Universitarias de Zaragoza, which is the only teaching manual that exists nowadays in Spanish.
